Health While Traveling 
No vaccination certificate is mandatory other than the yellow fever vaccination certificate if the tourist originates from or has transited through endemic yellow fever countries (Africa, South America, Papua New Guinea). You may consider inoculation against polio, measles, mumps, cholera etc. if you are a health fanatic.

Avoid eating from roadside food-stalls and never over-eat a cuisine you are not used to.

Always take care about the water you drink. If it’s not boiled avail authentic mineral water cans or bottles from shops.
